What documents do I need to travel with prescription medication?
Carry prescription medicine in its original labeled packaging with a doctor's letter and a copy of the prescription. Some common prescriptions are banned in certain countries.

The three documents to bring
Almost any trip with prescription medicine needs the same three things, and trip1 travelers heading somewhere with strict rules should sort them out before booking flights rather than the week of departure.
- A doctor's letter on headed paper, signed and dated, giving the generic name of the drug, the dose, how much you are carrying and why you need it. Generic names matter, because brand names differ between countries.
- The original packaging with the pharmacy label showing your name and the prescribing details. Loose pills in a weekly organizer are hard to explain at a border.
- A copy of the prescription, printed or as a clear photo, which also helps if you need a pharmacy while you are away.
Keep everything in hand luggage. Checked bags get delayed and holds are not temperature stable. Liquid medicines are exempt from the usual cabin liquid limit at most airports, but tell the security officer before your bag goes through.
How much you can bring
Most countries allow a personal supply, usually described as enough for the length of your trip or up to a set number of months. Carrying far more than your trip needs starts to look like importing, which is a different legal question with different paperwork.
Singapore, for example, limits personal medication to a three month supply and requires prior approval from its Health Sciences Authority for controlled medicines. Japan requires an import certificate, the Yunyu Kakunin-sho, once you exceed its personal-use allowance, and that certificate has to be arranged before you fly.
Medicines that are restricted or banned abroad
This is the part that catches people out. A drug prescribed to you legally at home can be a controlled substance or a prohibited import somewhere else, and in the strictest countries the penalties include detention and prosecution.
Stimulants prescribed for ADHD
Amphetamine-based stimulants are prohibited in Japan and cannot be brought in even with a prescription or an import certificate. Singapore and the UAE treat them as controlled substances that need approval arranged in advance.
Strong painkillers and opioids
Codeine, tramadol and stronger opioids are controlled in many countries. The UAE controls a long list of medicines, which need prior approval from its health ministry or a declaration with your prescription on arrival, and breaking the rules can bring serious penalties.
Cold and allergy medicines
Pseudoephedrine, found in some common decongestants, is tightly restricted in Japan: medicines with more than 10% pseudoephedrine need advance permission, applied for at least 14 days before travel. Several countries in the Gulf and parts of Asia also restrict it, and it is easy to pack by accident because it is sold over the counter at home.
Cannabis-based products, including CBD
Prescribed cannabis and CBD oil are illegal in many countries regardless of a prescription, and the UAE and Singapore are strict about both. A product that is legal at home does not travel with you.
Important: If a medicine is restricted or banned at your destination, the only safe route is to speak to that country's embassy and to your own doctor before you travel. Never relabel, hide, decant or split a prescription to get it through a border, and never carry a restricted medicine without the approval that country requires.
How to check before you go
- Write down the generic name and dose of every prescription and over-the-counter medicine you plan to pack.
- Contact the destination country's embassy or consulate, or its official medicines regulator, and ask directly whether each one is allowed and what approval it needs.
- Start at least four to six weeks ahead, because permits and import certificates take time to process.
- If a medicine is not allowed, talk to your doctor about a legal alternative for the trip, or choose a different destination.
- Repeat the check for any country you change planes in, because a transit country applies its own drug laws to what is in your bag.
At the hotel
Hotels do not ask about medication at check-in. If you need refrigeration for insulin or a similar medicine, message the property through your trip1 booking before you arrive and ask whether the room has a fridge or whether reception can store it, because an in-room minibar is not always cold enough or reliable.
Traveling with prescription medication - FAQ
Not for TSA screening in the United States: the TSA does not require medicine to be in prescription bottles, although some states have their own labelling laws. Abroad it is a different matter, so keep each medicine in its original pharmacy-labelled packaging. Loose pills in an organiser are hard to explain to a border officer.
Not for carrying them. The TSA allows medication in pill or solid form in unlimited amounts once it is screened, in carry-on or checked bags. Medically necessary liquids over 3.4 ounces are allowed in reasonable quantities, but you must tell the officer at the checkpoint so they can be inspected. Keep medicine in your carry-on.
For US airport security, generally yes, since the TSA does not require prescription bottles. The risk comes at your destination's border, where unlabelled pills can look like undeclared drugs. If you are flying abroad, keep medicines in their labelled pharmacy packaging and carry your doctor's letter and a copy of the prescription.
It is strongly advised and some countries require it. Singapore, for example, expects travellers to carry a prescription or doctor's letter. Ask your doctor for a signed, dated letter on headed paper giving the generic drug name, dose, quantity and your condition, and bring a copy of the prescription as well.
Some common ones are. Amphetamine-based ADHD medicines such as Adderall cannot be brought into Japan even with a prescription. Medicines with more than 10% pseudoephedrine, found in some decongestants, need advance permission, applied for at least 14 days before travel. Check each generic drug name with Japan's Ministry of Health or embassy before you go.
Usually a personal supply for your trip, with limits set by each country. Japan allows up to one month of prescription medicine without an import certificate, the Yunyu Kakunin-sho. Singapore allows up to three months' supply, and controlled medicines need approval from its Health Sciences Authority at least two weeks before arrival.
